Description

Combined structure of heat pipe and heat transfer base

technical field

The utility model relates to a combination structure of a heat pipe and a heat transfer base, in particular to a structure that can increase the contact effect between the heat pipe and the heat transfer base and combine the heat pipe with the heat transfer base.

Background technique

Generally, a heat pipe is applied to a heat dissipation device of an electronic product, and one end of the heat pipe is connected with an electronic heating component for heat transfer, and the other end is provided with a plurality of heat dissipation fins. With the high heat conduction capacity of the heat pipe, the heat generated by the electronic heating component can be transferred to the heat dissipation fins through the heat pipe, so as to discharge heat and cool down one by one. At the same time, for the heat accumulated between the heat dissipation fins, the heat dissipation fan can also be used to quickly drive away the heat to achieve a good heat dissipation effect.

Since the cross-section of the general heat pipe is in the shape of a round tube, the area after being flattened is not large, so in the past, the heat pipe is usually connected to the plate-shaped heat transfer base, and then attached to the electronic heating element through the heat transfer base. On the surface. As shown in FIG. 1 , it is a combination structure of a known heat pipe and a heat transfer base. It is provided with a groove 10a on the heat transfer base 1a where the heat pipe 2a can be placed. On the left and right sides of the groove 10a, there are respectively formed tabs 11a with protruding surfaces and which can be bent and deformed under the action of external force. . After pressing the section of the heat pipe 2a into a flat shape, the heat pipe is placed into the groove 10a of the heat transfer base 1a. At the same time, a tool (not shown) is inserted into the slot 12a located outside the two protruding pieces 11a, so that the two protruding pieces 11a are bent toward the heat pipe 2a by applying force, and then the heat pipe 2a can be positioned on the heat transfer base 1a. In order to achieve the purpose of combining the two.

However, since the heat transfer base 1a is only pressed on the left and right sides above the heat pipe 2a by using its two protruding pieces 11a, it is only a lateral downward pressure on the heat pipe 2a, and it is impossible to make the flattened The heat pipe 2a makes complete surface-to-surface contact with the bottom surface of the groove 10a. In other words, the two protruding pieces 11a only have the function of fixing the heat pipe 2a, but cannot ensure the contact effect between the heat pipe 2a and the bottom surface of the groove 10a, so such a combination structure is not designed with the concept of heat transfer technology in mind.

Therefore, it can be seen from the above that the above-mentioned known combined structure of the heat pipe and the heat transfer base obviously has inconveniences and defects in practical use, and needs to be improved.

Therefore, in view of the shortcomings of the above-mentioned prior art, the inventors devoted themselves to research and combined with the application of theories, and proposed a combination structure of a heat pipe and a heat transfer base that is reasonably designed and effectively improves the above-mentioned shortcomings.

Detailed ways

In order to enable your examiner to further understand the features and technical content of the utility model, please refer to the following detailed description and drawings of the utility model. However, the drawings are only for reference and illustration, and are not used to limit the utility model .

Please refer to FIG. 2 , which is a three-dimensional schematic view of the circular tubular heat pipe and the heat transfer base of the present invention. The present invention provides a combination structure of a heat pipe and a heat transfer base, which mainly utilizes the side plates 13 formed on both sides of the groove 12 of the heat transfer base 1 to enclose the heat pipe 2 and the heat conduction block 3 to pass through the heat transfer base 1. The heat conduction block 3 presses the heat pipe 2 to be formed in the groove 12 of the heat transfer base 1, and is combined for heat transfer.

First, as shown in FIG. 2 , the above-mentioned heat transfer base 1 , at least one of the above-mentioned heat pipes 2 and the heat conduction block 3 are prepared. The heat transfer base 1 is made of a material with good thermal conductivity, such as copper, aluminum, etc., and can be flat, and the top surface 10 of the heat transfer base 1 is concavely provided with a heat supply pipe 2. Inserted groove 12, so that the heat pipe 2 can be partially or completely placed in the groove 12 of the heat transfer base 1. Wherein, the groove 12 is recessed downward from the top surface 10 of the heat transfer base 1 and does not penetrate through it, but it may completely penetrate or not penetrate through the length direction of the heat transfer base 1 . At the same time, side walls 13 extending upward and upright are respectively provided above the left side and the right side of the groove 12 .

Please also refer to FIG. 3 , before the heat pipe 2 is combined with the heat transfer base 1 , the section of the heat pipe 2 is in the shape of a circular tube. The heat transfer base 1 and the heat pipe 2 are placed on the platform 4 so that the bottom surface 11 of the heat transfer base 1 is flat against the platform 4 . The top surface 10 of the heat transfer base 1 faces upward so that the two side walls 13 are vertically upward, and the heat pipe 2 is placed horizontally in the groove 12 of the heat transfer base 1 . And the heat pipe 2 and the heat transfer base 1 can be fixed and positioned by a mold (not shown). At this time, place the heat conduction block 3 above the heat pipe 2 again.
